What is the recommended practice to update or delete multiple entities in EntityFramework?

Question

In SQL one might sometimes write something like

DELETE FROM table WHERE column IS NULL

or

UPDATE table SET column1=valu         


        

Answer 1

Entity Framework Extended Library helps to do this.

Delete

//delete all users where FirstName matches
context.Users.Delete(u => u.FirstName == "firstname");

Update

//update all tasks with status of 1 to status of 2
context.Tasks.Update(
    t => t.StatusId == 1, 
    t2 => new Task {StatusId = 2});

//example of using an IQueryable as the filter for the update
var users = context.Users.Where(u => u.FirstName == "firstname");
context.Users.Update(users, u => new User {FirstName = "newfirstname"});
